Many people have likely noticed over the past while that the Overture keyword tools is extremely unreliable. Setting aside the numbers it provides (equal to or better than other options to be sure) one can rarely even connect to it.
Well we’ve found a quasi-successful workaround. For some reason (perhaps coincidence) it seems to work better in IE then Firefox. That’s not the workaround however. What we did find works more times than trying to connect directly to http://inventory.overture.com/ is to access it through Google’s cache of the page. Unfortunately this is far from reliable but appears to connect more times than a direct access attempt.
You can access the cache at http://22.214.171.124/search?q=cache:inventory.overture.com/. Note: it’s still not reliable – just better.
Note: Links removed as they no longer work.
